Faster source mirror #23062
Description
The spack default source mirror provides very low download speeds (at least in Europe). I have a 1Gb/s internet connection at home and usually reach around peak speeds, yet "fetch" times are a large part of installing a package:
zlib: Fetch: 2.37s. Build: 0.87s. Total: 3.23s.
libfabric: Fetch: 6.23s. Build: 9.54s. Total: 15.76s.
berkeley-db: Fetch: 12.91s. Build: 17.70s. Total: 30.61s.
cpio: Fetch: 4.73s. Build: 24.07s. Total: 28.80s.
cuda: Fetch: 4m 27.95s. Build: 1m 22.58s. Total: 5m 50.52s.
Can someone look into this?
